Question

Define dimension of physical quantity & find dimenstion of density ?​

Answer 1

Answer:

Dimension of a physical quantity is the power to which the fundamental units must be raised to, in order to represent it. Mass, length, time, temperature, electric current, luminous intensity and amount of substance are the fundamental quantities.

Dimension Formula of Density

1. Density typically means mass divisible by volume i.e. mass/volume. ...

2.Now, the Dimension of Mass = (M1)

3.Now, the Dimension of Volume = (L3)

4.Dimension of Density= {M1} / {L3} = M1/ L-3.

5.Unit of Density is kg/m3.
